殼牌220齒輪油-空壓機油宿遷沭陽縣泗陽縣銷售空壓機可以用46號油。 46號油具有良好的高溫氧化安定性、低的積碳傾向性、適合的粘度和粘溫性能、及良好的油水分離性、防銹防腐性等。它能在兩個摩擦物體之間形成一種保護膜，避免金屬與金屬之間直接接觸，從而緩沖了摩擦力作用，起到潤滑的作用，還可以減少磨損，從而使機械正常運轉(zhuǎn)Air compressors can use 46-grade oil. 46-grade oil has good high-temperature oxidation stability, low carbon deposition tendency suitable viscosity and viscosity-temperature performance, and good oil-water separation, anti-rust and anti-corrosion properties. It can form a protective film between two friction objects avoid direct contact between metal and metal, thus buffering the friction force and playing a lubricating role, and can also reduce wear, so that the machinery can operate normally
